keydctl - control an onak keyd instance

keydctl [ options ] command

keydctl is a command line client for interacting with a backend keyd daemon. It's intended to perform functions that are specifically related to keyd rather than being generic keyserver functions. See onak(1) for details about how to perform key related operations.

Use FILE as the config file instead of the default.
Display help text.

Query if keyd is running and accepting commands. Returns 0 if it is, 1 otherwise. Outputs nothing to stdout/stderr.
Request that keyd exits cleanly
Display the status of a running keyd. Currently the protocol version in use, when keyd was started, the number of client connections seen and a breakdown of the commands seen.

/etc/onak.ini	default configuration file

This man page could probably do with some more details.
